Neiko, that was wonderfully informative on its own. Thank you.
I've also wondered about cooking the soil in seperate bins, but how else would it be possible in a limited space? I'll give some thought to a bin on the balcony, though that would be useful only at certain times of the year. It would give me the capacity to cook the batch as a whole.
Interesting thought I too have split the soil into 2 batches
EDIT: Wanted to add just for informational purposes I have only
cooked 1st run soil, so no roots, leafs or additional items added yet
